If you enjoy FSX as much as I do, you MUST get this little scenery program. This is a game changer. You can activate scenery and place it in priority without even starting FSX. You can move your scenery priority around by simply dragging and dropping. It works outstanding. When you start FSX, your scenery is ready. I never use the Scenery Library within FSX any more.
A BIG thank you to the developers for making this wonderful program available.
Scenery Config Editor is one of the best things that has happened with FSX. If I could give it 10 stars, I would.
